The first part of your walk takes you through forests and Morvandelle meadows with magnificent views of the lake and the Chalaux valley. In the past, on the Bruyères bridge, there was an important port for floating wood. The logs were marked and stacked there until spring and then thrown into the river. They were then collected in Clamecy and assembled into a timber train, which sailed back to Paris. Wood from the Morvan heated the capital from 1550 to 1850. At that time, the Chaumeçon dam did not exist (and therefore neither did the lake). It was built in 1935 and helps to regulate the course of the Seine and to produce electricity. When water is released, the course of the Chalaux swells to the delight of white water sports enthusiasts. Its reputation as an impetuous river has led to the organisation of national and European competitions.
After leaving the banks of the lake, you can see a public saw bench at the exit of Brizon. It can cut logs from 6 to 12m long and is another witness to the importance of wood in the economy of the Morvan throughout history.
